Android: There are plenty of Android package-tracking apps to choose from, but few that handle a total of 37 shipping services (and fewer that do it for free). Parcels tracks packages shipped though services in several European countries, Canada, the U.S., Hong Kong and Japan, among others.

Parcels also has quick and simple navigation, allowing users to go from the list view of all their packages to the information pane for a single item. From the single-item screen, users can jump straight to the carrier's web-tracker to see all information attached to the tracking number, or map the package with a single click. Mapping will show the last-known location of the item on a Google Map, without leaving the app.

Users can choose to refresh tracking info manually, or have the app auto-refresh by interval and alert them to changes of status. When all packages have been delivered, it won't attempt to auto-refresh again to save on power-consumption. The app itself is also extremely light on memory, so it's not putting much of a dent in your phone's storage between online-shopping splurges.

Parcels is a free app for devices running Android 1.6 or newer, and is available at the Android Market.
